Lyne AMP 35 Stem 50mm
What Is It?
The Lyne AMP 35 Stem (50mm) is a mountain bike stem designed to connect your handlebar to your fork steerer tube. It’s part of Lyne’s AMP cockpit range, built specifically for modern wide handlebars and trail MTB riding.
The “50mm” refers to the stem length, which gives a balanced mix of stability and steering control—more stretched than a 35mm stem, but still responsive for trail use.
Key Features
- 50mm stem length (balanced MTB setup)
- 35mm bar clamp diameter (for modern wide bars like Lyne AMP bars)
- 6061 aluminium alloy construction
- Zero-degree rise (neutral cockpit position)
- Reinforced faceplate for stiffness and control
- Designed for wide MTB handlebars (760–800mm range)
- Built for trail, XC, and all-mountain riding
Specifications
- Material: 6061 aluminium alloy
- Length: 50mm
- Bar Clamp: 35mm
- Steerer Diameter: 28.6mm (standard MTB fork)
- Angle: 0° (neutral)
- Weight: ~196g (50mm version)
Bottom Line
The Lyne AMP 35 50mm stem is a solid, reliable MTB stem for riders who want a balanced feel—not too twitchy, not too stretched out. It works best with modern wide handlebars and gives a stable but still responsive front end.
It sits right in the middle between:
- Short 35mm stems (more aggressive, quick steering)
- Longer 70–90mm stems (older XC stretched position)
Who Is It Suitable For?
- Trail and XC mountain bikers
- Riders using wide modern handlebars
- Intermediate MTB riders
- Riders who feel 35mm stems are too twitchy
- Riders who want better stability on descents
Pros
- Strong and stiff alloy construction
- Balanced handling (not too short, not too long)
- Good compatibility with modern MTB setups
- Reinforced design for wide bars
- Affordable performance upgrade
Cons
- Heavier than carbon stems
- Less agile than 35mm stem on tight trails
- Not ideal for downhill racing setups
- Fixed angle (no adjustability)
Who Should Use It?
You should use this stem if you:
- Ride XC or trail MTB regularly
- Want more stability than a 35mm stem
- Use wide handlebars (750–800mm)
- Prefer a neutral riding position
- Are upgrading from a longer or outdated stem
